Big Walk achievements: all 12 and how to unlock them

What this Big Walk trophy guide covers

Steam’s official Global Achievements page lists 12 Big Walk entries. Ten show a short public condition; Big Goodbye and Big Game have blank conditions on that page. We checked the list on October 1, 2026. The area-by-area route notes are attributed to IGN’s public community guide, marked updated August 11, 2026.

The developer’s official FAQ confirms general game and platform information but does not publish an achievement master list. The short routes in this guide are editorial summaries; do not read them as developer-authored step-by-step instructions or proof that every platform tracks the same list.

Use the table to find an objective by name, then open the matching area section for a reported route. The groups are for quick lookup, not a mandatory order: Big Walk is open world, so a group may encounter objectives at different points in its session.

The three screenshots are developer-published media showing co-op exploration, a landmark and a station. They add setting context only; none is an achievement pop-up or evidence that an objective has unlocked.

All 12 Big Walk Steam achievements at a glance

Drawbridge and early gear achievements

These objectives sit near the move from the tutorial area into the main island, plus the first equipment discoveries. Do not treat the order below as mandatory: the source says open-world progress can change the order in which trophies appear.

Big Walk · Tutorial exit

Short answer: Cross the red drawbridge and enter the main island.

The reported route is to solve the tutorial area's four puzzles, take the key to a grinder, and use the resulting key to open the red drawbridge. Crossing the bridge is the unlock condition; simply reaching the bridge is not enough.

Big Pack · Early exploration

Short answer: Wear a backpack; the earliest reported one is near the Red Tower.

Look for a backpack at the blue structures that house wearable gear. Pick it up and put it on. The guide identifies the area near the Red Tower as an early place to find one, but it does not require a specific color or style.

Big Help · Early exploration

Short answer: Wear an item on your hip.

Check the blue gear structures for a hip pack as well as a backpack. Equip the hip item to meet the condition. This is a separate objective from wearing the backpack, so one item does not substitute for the other.

Tower keys, travel and exploration achievements

Several listed objectives use a tower key to open a route or destination. The route below keeps each named tower attached to the right unlock, which is more reliable than guessing from a screenshot or assuming every tower is completed in a fixed sequence.

Big View · Red Tower

Short answer: Visit the map room after unlocking it.

Complete the Red Tower, carry its key to a grinder, and use the key to open the map room. Enter the room to register the visit. The reported condition is reaching the map room, not collecting every map marker.

Big Ride · Blue Tower

Short answer: Ride the train after opening the main train station.

Complete the Blue Tower and grind its key, then use it to unlock the main train station. Board and ride the train. Reaching the station alone is not the condition described by the guide.

Big Tunnel · Yellow Tower

Short answer: Enter the large tunnel after unlocking it.

Complete the Yellow Tower, grind its key, and open the tunnel entrance. Follow the key grinders toward the opening if you need a route cue, then go inside. The achievement is tied to entering the tunnel.

Big Makeover · Tunnel area

Short answer: Use the color-changing station hidden inside the tunnel to get shiny.

First unlock the tunnels through the Yellow Tower route. Then look inside the tunnel for a second color-changing station and use it. The phrase “get shiny” is also a searched variant for this achievement; the source connects it to this station.

Big Sit · Green Tower

Short answer: Ride the chairlift after unlocking it.

Complete the Green Tower and take its key to a grinder. Use the key to open the chairlift, then hop on for a ride. The source says the key grinders point toward the chairlift, so follow those if the entrance is not obvious.

Big Climb · Mountain summit

Short answer: Continue upward from the chairlift's highest point until you reach the marked peak.

Ride the chairlift to the highest point of the mountain and get off. Keep moving uphill rather than stopping at the lift endpoint. The guide says a red symbol marks the highest peak; reach that point to satisfy the reported condition.

The ending and post-game achievements

The two completion trophies are easy to confuse. IGN separates finishing the story from completely finishing the game, so leave room for the post-game activities if you are aiming for the final item in the list.

Big Wall · Beyond the wall

Short answer: Open the Big Orb area with the Black Tower key and go beyond the wall.

Complete the Black Tower to obtain its unusual black key, then use that key to unlock the Big Orb area. Continue beyond the wall. The guide treats crossing into that area as a distinct achievement before the final story puzzles.

Big Goodbye · Story ending

Short answer: Finish the remaining puzzles beyond the wall and reach the end of the game.

After Big Wall, complete the last several puzzles and finish the story. The guide describes this as saying goodbye to your friends. This is the story-finish objective; it is not the same as clearing all post-game content.

Big Game · Full completion

Short answer: Earn every other trophy and finish everything available in the post-game.

The IGN guide describes Big Game as completely finishing the game. Its note includes every trophy and the post-game activities. If Big Goodbye is unlocked but Big Game is not, return to unfinished post-game content and check for any remaining objective in your platform's achievement list.

Platform, source and spoiler notes

Steam’s official list shows 12 entries, but the developer FAQ does not publish a cross-platform achievement count. This guide does not assert that PS5 trophy numbering, a Platinum trophy, or Switch 2 tracking exactly matches Steam. Check the list shown by the platform you are playing.

On the Steam page checked here, Big Goodbye and Big Game have no public condition text. We describe those as entries with blank Steam conditions; we do not infer how another platform labels or displays them.

Big Wall, Big Goodbye and Big Game point to late-game areas. Stop after the table or early gear section to avoid the later route and story details.
